Improved understanding and new formulations of the

fundamental laws of nature

Interpretation of current and future experiments collider physics

Large scale computing, computer algebra, parallel computing

Theoretical concepts and calculational tools



Precision Calculations



multiloops 4-loop massive tadpole amplitudes 4-loop massless propagator amplitudes large demand on computer algebra

• SUSY and renormalization

• computer algebra and parallelization (PARFORM)

conceptual developments:



• precise quark masses (world record)mc = 1286 13 MeVmb = 4164 25 MeV

• evaluation of in completed

GIGA-Z • NRQCD - effective theories - QCD potential - bb bound states

• top quarks at threshold and in the continuum

• radiative return at DANE and B-factories at low energies

Collider Physics

Tevatron

LHC

ILC



• NLO QCD calculations loop corrections for LHC processes

• Higgs physics - measurement of Higgs couplings at LHC - anamalous couplings in VBF processes - central jet veto against VBF backgrounds - Hjj events from gluon fusion - Higgs physics in the MSSM

• Parton shower Monte Carlos - development of Herwig++ (Helmholtz Alliance "Terascale")



• top quark physics QCD and electroweak effects

• gauge boson, quark and jet production at large momentum transfers
